〜なさそう: doesn't look like; seems not to

Says that something looks as if it is not there or not so, based on appearance.

Adjective: drop い and add なさそう (おいしくなさそう, よさそう for いい). Noun/state: がなさそう (お金がなさそう). It is a guess from how things look. For verbs that probably will not happen, use 〜そうにない/〜そうもない instead.
